  • METHODS FOR FRAGMENTING IONS IN A LINEAR ION TRAP
    Publication number: 20090194686
    Abstract: Methods for fragmenting ions retained in an ion trap are described. In various embodiments, a non-steady-state pressure of a neutral collision gas of less than about 5×10?4 Torr and an excitation amplitude of less than about 500 mV (peak to ground) is used to fragment ions with greater than about 80% fragmentation efficiency. In various embodiments, duration of ion excitation is greater than about 25 ms.

  • DYNAMIC PIXEL SCANNING FOR USE WITH MALDI-MS
    Publication number: 20080017793
    Abstract: A method for dynamic pixel mass spectrometric imaging, or dynamic pixel imaging is disclosed. The method includes striking a sample to be scanned with a laser beam so that the laser beam releases analytes from the sample. The laser beam and the sample are then displaced relative to one another so that the laser beam substantially continuously traces a predefined path on the sample to release analytes from the sample along the predefined path. A mass analysis of the released analytes is performed.
